|Thread: New Lathe - cleaning the oil off|
Kerocene (paraffin) and an old rag.
|Thread: Machine Tool Peripheral Hoists|
A lathe that has a 500 lb chuck would be a BIG lathe
|Thread: Synthetic and enamel paint explained|
I'm only an amateur spray painter and have painted a car with celulose type paint which required a lot of work to get a good finish. Lots of rubbing back between coats and buffing the final coat to get a shine. But it does look good.
I've just painted my traction engine with 2 pack paint which is much quicker. The panels were sand blasted and an etch primer applied, followed by a normal 2 pack primer and rubbed back with wet and dry paper. Then 2 colour coats. No clear coat and no final buffing required for a shiny finish. Probably not as good as I achieved with the celulose paint by applying a clear top coat, rubbing it smooth with fine wet and dry and buffing to get a shine but trying to cut and buff around all the rivet heads on my engine would be almost imposible.
But as mentioned, you do need to wear the correct PPE because it is cancerous if you breath the fumes. I also did the painting outside.
|Thread: Stand for Dremel type power tool|
The toolstock adaptor for my Dremel is very simple and made from a scrap piece of aluminium.
The plastic threaded sleeve that the grinder screws into is made from one of the unused accessories that came with the grinder. Therefore did not have to make a thread, just bore a hole in the adaptor to hold it.
|Thread: Toothe broke on lathe chuck|
"How should i be loading these into the chuck?"
Load the jaws in the normal sequence, starting with No 1 but skip the one with the missing tooth.
eg. If the first spline on No2 is broken. Rotate the sctroll and engage No 1, then continue to No 2 but as it is broken keep going and engage No 3. When the start of the scroll comes back to No 2 position, you can engage the second spine.

|Thread: Can I combine primers on aluminium?|
I am not familiar with the Normfest product but etch primers which contain acid are often used on aluminium to give good bond but can only be used on bare metal. They will not adhere to filler material. Maybe why the instructions say to only apply one coat. Etch primers should be given a coating of a normal primer prior to the colour top coats.
Cannot comment on your ferrous primer without details. Best to find a data sheet for it.
|Thread: Source for wiper felt|
The wiper holders on my 9" Southbend lathe are a similar shape.
Felt used to be used as an underlay for carpet. Not sure if it is still available but may be another source for material.
Try searching for industrial felt or felt for bearing seals. Possibly from bearing and shaft seal suppliers.
|Thread: DIY Electric welder|
Found this link to a cheap DIY electric welder.
And I do mean CHEAP !! Would I use it ? NO
Something that I learnt somwhere told me that salt water and 230V of electricity do not mix. What are your thoughts ?
|Thread: Making a centre finder for the mill|
Informative video and straight to the point without listening to someone who likes the sound of their own voice. The video has also been edited to take out unwanted frames and keep it short. (I normally switch off long winded posts and never watch them to the end)
|Thread: Which Digital Compact Camera?|
I have a Lumix DMC-TZ110 and is the 3rd Panasonic that I have owned and very happy with it.
Features include a 25-250 Optical zoom and a 1" optical sensor. and takes 4K video. A single frame of the video can be captured and make an A3 sze print. Heaps of auto or manual modes including apteture priority, speed priority. Burst mode takes a series of shots and chose the one you want later is great to capture action photos. Or post focus and chose the focus length after you have taken the photo.
The price is at the top end for a compact camera but has most of the features of a big camera in a smaller size.
|Thread: Mill recomendations ?|
Do a search for mill, milling, small mill, etc. There are many posts on this forum discussing the choice and use of a mill.
|Thread: New Steel Boiler for under £200|
Not sure of your boiler code in UK but here ia Australia MIG is not allowed. MMA (stick) or TIG only for model steel boilers.
|Thread: Rotary Table Chucks|
I find that a 4-jaw chuck is more useful as it can hold odd shaped parts. Getting round parts on centre does not take very long with a dial indicator.
I have an RT with 4 slots and the 4-jaw chuck has 4 thru holes and can be bolted to the RT without a backing plate and a spigot keeps it central. Not having a backing plate allows you to fit a larger chuck (same diameter as the RT)
|Thread: Tig Welder recommendation|
" using your foot & hands together " Like driving a car !
|Thread: How are your clubs responding to Coronavirus|
Everything is very quiet in Sydney.
The model steam locomotive club that I belong to is closed. Also my other club at Maitland (north of Sydney) where we run 12" : foot engines.
April was to be our annual Steamfest rally which we hold in conjunction with the town council and other clubs, attracting up to 50,000 visitors. Two full size steam trains were coming and we had ~15 full size traction and stationary engines and 100+ vintage and modified cars.
Disappointed that I could not go to Steamfest, I attended Homefest to get my fix of steam. **LINK**

|Thread: Thread to discuss Solid Edge 2D and 3D|
Learnin to use a 3D CAD prrogram is not an easy task. It is a new language and will take time to master. (how long would it take you to be proficient in Mandarin or Russian, etc).
I have not used Solid Edge but have been a CAD draftsman for 10+ years, now retired. It took us 3 months to master Pro Engineer when it was introduced. When I changed jobs and used Solidworks, I was sent to a full week of training to learn the basics and later anther week to learn the advanved features and still learning.
Software is more friendly now but still takes a lot of study and practice. Stay with it as it is a great resource and has saved me heaps of time in the workshop. Cheaper and quicker to find problems and fix them in the computer than on a lathe oe mill.
|Thread: Cross slide dial calibrations - opinions sought.|
Add a digital readout.
Even modify a digital caliper and you can switch between metric and imperial. A cheaper setup will not solve the radius / diameter problem but will be much easier to read.
|Thread: Shaft Tolerance|
All press fit bushes will compress if pushed into a hole for an interference fit and is why the manufacturers specify a toleranced hole to suit.
Machining your own bushes is a different matter but if made to correct engineering standards should be made to the recommended tolerances in the table that Jason referenced. The bodge way out is to make the bore to the required diameter and the OD undersize to the hole and Loctite it into position.
" What size do I machine the shaft to to ensure the snug fit" The shafting diaqmeter is normally the controlling dimension and the bush bore made to suit.
|Thread: Ball Nose End Mill / 10V Bearings Question|
Bull nose cutters do not have an accurate radius as you have found. A better radius would be achieved by using the side of the cutter and machine from the side of the work. Use a cutter with a slightly smaller diameter than the slot will allow you to open it up to the correct width. (the radius would not be purfect but better that using the tip of the bullnose).
Another option is to use a cutter which is the width of the slot and cut from the side of the cutter. (the buttom of the slot will be a purfect radius) and make the bearing to suit the slot.
