|Thread: hobbymat milling machine|
Welcome to the forum. If you don't already have a manual, there is a Prazi-group on groups.io where you should be able to find a manual.

|Thread: Benchtop lathe with power cross feed, looking to buy|
In addition to the Sieg SC4 you could also consider the Warco WM 250V with an inverter driven AC motor or a WM 280/290 lathe if you want a larger lathe.
|Thread: Silver Soldering Materials|
You should be able to buy both brazing rods, flux and a propane torch from CuP Alloys. A butane blowtorch may be enough to silver solder(braze) small items if you can make a small hearth to prevent the heat from escaping too fast.
|Thread: Boxford Metric conversion gears info|
There is a Boxford group on groups.io that is still active.
|Thread: Oil Blackening and other Oil Issues|
I use linseed oil to blacken small steel items. Heat the steel to about 280 to 300 deg.C and apply the oil with a small piece of rag. I burn the rag afterwards, it may self ignite.
|Thread: Rollo Elf Lathe|
Welcome to the forum. I assume you have already found this site, and it seems you can get some literature about your lathe. If you have - or can get centres - that fit headstock and tailstock you should be able to do some turning. If there is a club near you you may be able to get some help there to cut the required thread on a faceplate or backplate.

|Thread: Holding drills in ER collets|
I too use my ER chuck for holding drills, especially for accurate work and if the drill has the same diameter as one of my collets so I don't have to compress the collet much. My cheap drill chuck has more run-out than the collet chuck.
|Thread: Er25 collets|
Hi Oly Rag,
I got an Imperial ER-32 collets for 1" shanks just before Xmas but haven't had time to use it yet. It is shorter than the 20mm collet. I got my 1" from Ebay - Gloster Tooling.

I have ER 32 collets that cover most of the sizes I use. I did buy Imperial ER collets for 1/8" from Arc since I have a couple of tools with 1/8" shank. Clamping a 4mm metric ER collet down to 1/8" may reduce the accuracy so I bought the Imperial collet. If you use many imperial tools a 1/4" and may be a 3/8" collet may be worth the money. A 16mm ER collet will easily clamp a 5/8" shank tool.
Best wishes to you all for a better 2021.
|Thread: Shimming Techniques|
I assume Ron is talking about these?
|Thread: Workshop time|
You are right, during winter I use an electric heater with a thermostat, my workshop is in the basement of my (old) house so it is reasonably well insulated and the temperature stays comfortable except on very cold days.
During summer I rarely use the workshop, but I try to get a few hours in the workshop each day during the winter season.
|Thread: Milling machine tooling|
I assume you already have a milling vice and clamping kit for your milling machine. As Pete says, buy some more collets or a collet chuck, I use ER collets since I can use them both on the milling machine and on the lathe to hold round work. The collet sizes I use most are from 3mm to 16mm. The sizes you need depends on what kind of work you do. Harold Hall's website has a section about grinding, cutters must be sharp.
|Thread: Mery Christmas Everybody|
Merry Christmas and a Happy New Year to you all.
|Thread: Thread Dial Indicator Chart?|
I agree with Bazyle, when I made a 28T gear for my 290 lathe to cover pitches not covered by the 30T standard wheel I used a Module 1 gear cutter. That worked well, I guess my depth of cut was slightly deeper than usual.
|Thread: Lathe stand information|
Welcome to the forum. I have a 290 lathe so should be similar to yours. I didn't buy the stand but I have included the foundation drawing. May be that can give you some help.
|Thread: Reducing round stock|
For such a short distance I assume you could use the same technique with your milling machine.

|Thread: After lathe manual|
Welcome to the forum. The only Denham manual I have managed to find is this.
