zini 1,939 Posted June 22, 2011 Report Share Posted June 22, 2011 (edited) Hi lads, Not sure if this should of gone in the General or Technical section. If its in the wrong section I apologuise. I'm after someones help please if possible from someone who has a lathe and will do me a small job. I will be quite willing to pay for the labour and material costs via paypal up front if needed. I need 4 washers making on a lathe for a project Im doing on a Theoben MFR in .177 calibre. The 4 washers are broken down into 2 designs. Part A and Part B. I need 2 x A and 2 x B making please. I have put together a diagram of what i need with the dimensions. If someone would kindly assist me that would be great. Cheers in advance Si. Edited June 23, 2011 by zini Quote Link to post
andyfr1968 772 Posted June 22, 2011 Report Share Posted June 22, 2011 I have access to a lathe, Si, but it's a basic old thing that lives at a mate's house. I'll show him your requirements but I'm not sure it'll go that fine. I'll drop you a PM once I've spoken to him. Cheers. Quote Link to post
zini 1,939 Posted June 23, 2011 Author Report Share Posted June 23, 2011 Cheers Andy pal. If it wont go to .8 of a mil to the mil would have to due pal. In the mean time if anyone can assist please let me know. I am going to design a mod for a MFR shroud. Here is the finished design Si. Quote Link to post
zini 1,939 Posted June 23, 2011 Author Report Share Posted June 23, 2011 Just changed the washer design Andy by 1 mm. The first diagram is now correct. Cheers Si Quote Link to post
andyfr1968 772 Posted June 23, 2011 Report Share Posted June 23, 2011 I've just had a closer look at the design, Si. Are you sure a drilled centre tube is the way to go? That system works OK for powder burning guns where flame flash is an issue but with an airgun, it's not as effective as just keeping the sound absorbing material out of the pellet's path with some kind of mesh. I know that HW do literally use hair curlers, but what could be better for the job in an airgun? I know it sounds gash but if you think about it, why not? Cheers Quote Link to post
zini 1,939 Posted June 23, 2011 Author Report Share Posted June 23, 2011 (edited) Yep I here you Andy. The above design is design 2 of 2. I also have the parts for mark 1 design here. Want to make the parts for both to trial which is best buddy. Ill then stick with the best and quietest Si Edited June 23, 2011 by zini Quote Link to post
andyfr1968 772 Posted June 23, 2011 Report Share Posted June 23, 2011 I'll give you a shout as soon as I've spoken to my mate. Quote Link to post
zini 1,939 Posted June 23, 2011 Author Report Share Posted June 23, 2011 Thanks Andy buddy Si Quote Link to post
matt_hooks 188 Posted June 23, 2011 Report Share Posted June 23, 2011 Hi Si. What material are you looking for these in? It might be worth considering delrin or similar for an airgun, lighter, cheaper and easier to machine than steel/ally. If I had access to a lathe I'd knock those up in a few minutes for you. I'll see if I can find someone who'll give me a little time on theirs. Quote Link to post
secretagentmole 1,701 Posted June 23, 2011 Report Share Posted June 23, 2011 Zini if no use PM me, my gunsmith has a lathe and does work very cheaply (his workshop/shop is on his parents land etc). He could knock those up in a jiffy, let me know if you are having trouble and I will PM you his contact details! Quote Link to post
zini 1,939 Posted June 24, 2011 Author Report Share Posted June 24, 2011 Cheers Matt and Mole Ill keep you both updated. Si Quote Link to post
airtech 39 Posted October 31, 2011 Report Share Posted October 31, 2011 hi i have many lathes in our workshop but looking at what you intend to do is just a extension to the barrel and the gains you will get are not worth spending your money on in our opinion you should do away with the tube that has the small holes in when i first started making silencers i went down the same road as you but soon changed our disign and now our silencers are one of the best on the market airgun rimfire and centre fire with a silencer the best way to go is making the baffle hole as close to bullet or pellet dia as you can you will find that making it like that will work remember not to make all the chambers the same lenght other wise you will just take one level of noise from the fired gun because the chamber lengh in silencer is the same as the first second on on and dont make the body to thin otherwise it will ring when you shoot it that is common on some silencers for centre fire guns Quote Link to post
deano26 16 Posted November 1, 2011 Report Share Posted November 1, 2011 If you have trouble getting them knocked up i can see if i can get an hour in our tool room at work and make them up for you mate. Regards Dean. Quote Link to post
