|Thread: EN40 nitrided repair|
Depth of nitriding will depend on how long it was done for so may only be 0.008"/0.0012" deep.
Speak to your heat treater who did the process it is possible to reverse it back to where you started at the risk of a little distortion. I have had this done with "P20" (Din 2311/2312)
Can you do the division lines yourself with a simple pointed tool either on the lathe or mill ? This would reduce the cost. Some engravers up here in the Midlands but getting fewer as the industry declines. Diegrave in Walsall come to mind as one still going
|Thread: Just a small problem|
Is there enough metal around the area to go even bigger? Drill/tap and plug off using a dab of studlock to hold the threaded plug in place then redrill to suit 7BA? Remachine the plugs flat before redrilling.
|Thread: Binding leadscrew.|
Reman, welcome along to the forum. My take is to keep life simple and I would just shim it until it works well then leave well alone.
|Thread: 5C Collet stop/centre|
Only my newer 5C collets have the internal thread for a stop. Most of mine came with a long departed South Bend lathe from 1942. I have replaced a few and added some metric and hexagonal ones but the rest are still good. Nice work on the stop, I think the standard stop set up is 3/8 unf.
Graham, thanks for the reply. Martin Bratby is based not to far from me so I will try him first.
I have not fitted circlips to a piston for years, preferring to use aluminium or Teflon/glass filled ptfe type buttons. From that you may well tell I am a pre war BSA man. I am doing some bits for a friend with a Velo and he wants me fit wire clips as original.
Graham, in your Velo tatt box would you have a 3/4" x 0.040" wire circlip with "ears" for a KTT gudgeon pin ? or know where I can get one ? Most suppliers now just sell snap rings. Good luck with the gear cutting. Chris.
|Thread: Hi from Devon|
Welcome along Simon,I have a 1929 BSA Sloper and a 1932 BSA Sloper to play with plus a Yamaha if I want to go anywhere...… Enjoy the forum.
Graham, please let us know how you get on. I have a bit of a collection of knackered tufnol gears.....
|Thread: Digital calipers made in same factory?|
I have said before on digital calliper posts that I use Aldi ones as every day tools. Every bit as accurate and smooth as my Mitutoyo and SPI branded ones. I butchered an Aldi 6" one to make a readout for the lathe tailstock around 18 months ago, still running on its original battery. The posh ones do come out of the box for some jobs but by the very nature of design are not really that accurate if you are chasing precision. Most of my jobs are only to a couple of thou so a calliper does the job and at £8 it does not matter if it is dropped.
|Thread: RENAULT DAUPHINE|
I bought a rusty one for £3 to rob the tufnol timing gear from to put in my Renault 4. The rest was scrapped.
|Thread: Searching for an Off-The-Shelf, Light-Duty, Rack & Pinion|
HPC are my go to, also look at Duval Gears. I think your 6/8mm square bar is a dream that will be flexible there will be no strength or any depth for the tooth form. Start thinking around 15x20mm.
|Thread: Little experience so advise needed|
Chris, where in the world are you based ? for practise turning you won't go far wrong with EN1A. Then buy your "Blue Pivot Steel" if you are close to Lichfield I can give you some bits to play around with.
|Thread: Laser cutting service|
Not sure where you are based but in the Midlands I use NRS laser in Tamworth. Good service and very reasonable prices. You do need to send him a DXF file though. Speak to Nathan if you use them.
I have been away on holiday so have missed all the posts over the last week. Andrew I respect your decision and will miss your input. I to use large machinery for my motorcycle work and being a retired toolmaker have some knowledge to pass on. Your leaving will be the forum's loss.
|Thread: Different ways of boring a hole|
|Thread: My new lathe a Warco 918|
Ron, do not worry about the age of your machine. I have an Excel branded 14"x40" lathe made in Taiwan in 1996.
Second hand when I bought it and has done a lot of work over the last 8 years in my ownership. No accuracy problems but I did have to make a new cross slide, partly due to wear mainly due to abuse by former owner. I wanted to beef it up and add tee slots so a worthwhile mod.
|Thread: Forging brass; how easy would it be?|
Andrew, I have looked at my stock and have nothing over 2" for you. The 2" piece I found is about 3 1/2" long and has still got the price on in felt pen. £3 I usually pick up useful bits and bobs from the bike shows. Chris.
Life's to short and the gas will cost near as much as an offcut. I would just buy a piece. I often see small offcuts at the motorcycle autojumbles and shows, I will check my stock I may even have a piece, where are you ?
|Thread: Hello from Belgium|
