New cast parts, round 2

[Ben]

Thanks for the vote of confidence.

Doing the lower and upper bolts isn't a problem but I suspect the price may be. There is a minimum charge for casting parts so I think that they could easily cost £5 each. The other issue is that the top one needs to be tapped, this is easy you can all drill out a hole and run a tap down the centre. The bottom screw will need to have a thread cut too but using a die, the threaded section will need to be turned down to allow the die to run down it's length. This will need to be done on a lathe yourself or it involves me getting them done which will add to the cost. How many would want one if the cost stared pushing £10 each!!

I'll post a new thread over the weekend about two new parts that are ready to be done.

Sorry to put a downer on the bolts but I can't see a cheap way of getting them done but I will ask at the foundry next week.

Thanks

If there is enough interest, I could get a qoute from a foundry here in London for the thumbscrews on the lower engine panels for the folks here in Canada. Could save a little on postage. I would need 6 to complete my machine.
Not wanting to steal your thunder Ben, but we could have a comparative quote for the screws, and perhaps send to the UK.

Perry, I would be interested in the 8 lower cover thumb screws. Ben, could you confirm the price for the casting minus machining?

[Doug Lavoie]

Perry,
Same info. as Jordan. Hope it all works out.

[Ben]

I've got no issue with getting them cast, I'll ask this week. I was only trying to point out that the post machining "may" need a lathe. As soon as I have a price I'll post it.

On closer inspection, I think the thumb screws are forged. They have a wide seam on the shoulder and the part number is stamped in. I am also going to get a quote on having them machined from round stock, that would also supply them finished.
Ben is correct. Chucking the cast screws up in a lathe to turn and possibly thread would be getting expensive. Some might think machining from bar stock would be expensive as well. When I get the quotes, will post prices.

Are we talking about the upper round knurled knobs(one type only) with the internal (female) threads, that hold the upper engine side covers at the top,
Or are we talking about a male threaded wing nut type stud (at least two types) that hold the lower engine side covers in place,
or..... are talking about both or something else?
