Thread: Sino SDS-2MS Dro problems
13/06/2019 11:21:59

Hello Mike

I wonder if you were to resolve the this issue with your SDS2MS ? I have been having the exact same issue with mine. I have had it for many years but recently decided to try and put it to greater use and like you when I tried to carry PCD function my problems started. Like you Allendale sent me the SDS 6 manual but this was of no help. I am talking to Allendale but so far they have not been able to offer a solution.

Kind regards

Alan Gordon

Thanks Jason You are probably aware I am still on the learning curve, however I have to say that the Firefly is coming along well, so looking forward to its first run soon

Wonderful this is exactly what I was after. Just another thing Jason, I also have completed cons rods as you have done however how did you over come the problem of the cutter "digging in" while turning the con rod in the chuck /rotary table.I found that "very gentle" cuts plus a good grip was required but is there another way that I need educating in ?

Thanks for that Les, very interesting.

Hi All, Well I am on the final lap of completing The Whitaker "Firefly" I have to say it has been a steep learning curve, but getting there, There is however one part that is throwing me and that is machining the prop driver, The outside is not an issue but machining the internal "flat" to locate on to the crankshaft. I could secure with a grub screw but would like to learn how to machine the internal flat. Any help would ( believe me ) be greatly appreciated.

Thread: Duralumin

Sincere apologies: The back issue I am after is March 2012, ( as stated on the plan ) however it is RCM&E not ME !! I will have to read things just a bit more carefully, lol

18/11/2018 17:24:00

Afraid not.

Thanks for that Jason, It is indeed to be used for a con rod, In fact I know you know the engine very well : Firefly 46. Can I take this opportunity of thanking you for an excellent build article

Thread: grade of Aluminium
30/09/2018 09:51:16

Hi, I am turning down a piece of aluminium round stock, the chips that are coming of are like grains of sand ? i have tried different speeds and inserts but the chips remain the same. I notice on the end it is coded red so my question is this can anyone suggest what grade of aluminium this might be ?

Hi, Guys

I am at present building a small IC glow engine which calls for "212m36" EN8 steel for the crank shaft. Can anyone recommend where I might purchase a small length ? I have tried the usual suppliers to no avail.

Any help would be appreciated

Thread: Myford belts
21/09/2018 21:17:02

Gentlemen, Many thanks for your advice and help, I have ordered the two belts from Lathe Spares.

21/09/2018 10:34:55

Hi Guys. I would like to replace the belts on my Super 7. I was thinking on using link type belts for ease of installation any advice and help would be appreciated ie general thoughts, where would I get them, sizes etc.

Thread: Boring Head
17/05/2018 12:52:09

Thanks guys for your advice, I have taken all advice and I believe the problem was backlash. I ensured that I took out as much backlash as possible on X and Y axis and kept checking my DRO to ensure that 0.000 was always showing with no drift. Mission acomplished.

Hi Guys, I have scrapped a small crank case due to the bored hole being off centre !!

I have started a new crankcase and ensured that all was centred and locked down, I installed a new Vertex boring head and a new cutter and turned the head by hand very slowly, I was amazed to see that when the cutter was set to just graze the inside surface of the pre drilled hole but when turned 180 Degrees it wanted to over cut ? This why the first hole was off centre. I am sure I am doing something daft but I cannot figure this out. Any help would be appreciated.
