Does anyone have any good ideas on how best to model the strange spark arrestor the Frisco used on most of their H10-44's and all of their H12-44's? Was this a home-built item, or is it a spark arrestor other FM's used? Is it available as a detail part in HO? I haven't been able to find it. Given the two new Walthers P2K H10-44's available in Frisco colors, and the old Walthers FM I have on my shelf that I'm making into a H12-44, these "sparkys" are in need! Ken
Ken .. #279 here shows TWO of the regular? type sparkies placed abeam each other- if this helps. http://www.rrpicturearchives.net/showPicture.aspx?id=114891
It looks like one of these two is what you are looking for: Detail Associates 229-2101 http://www.walthers.com/exec/productinfo/229-2101 or Details West 235-123 http://www.walthers.com/exec/productinfo/235-123
Indeed! In looking through all my H10-44 and H12-44 pics, I come to the following conclusions: - Some SLSF H10's had spark arrestors, some didn't, even into the orange/white stage. - All the H12's had a single screen spark arrestor covering both stacks. This is the item I was asking about. Some, but not all, of the H10's also carried this type of spark arrestor. - Other H10's used the "lifting" type of spark arrestor sirfoldalot and klrwhizkid noted. This is the same type spark arrestor generally used on Frisco's E7's, E8's, F3's, F7's, GP7's, FP7's and re-engined ALCo FA's. Each arrestor covers only one stack. - At least one of the H10's (slsf 279) had the two lifting spark arrestors mounted side-by-side, one on each stack, oriented along the length of the hood (same way they were mounted on the F's & E's, but side-by-side). - Other H10's, in fact several, had the lifting spark arrestors mounted side-by-side, one on each stack, but oriented sideways, at 90 degrees to the length of the hood. Enough pics exist of the H10's without any spark arrestors such that the new Walthers model will look just fine without them. If one were to want to use spark arrestors on an H10, I'd suggest the Details Associate part as it is finer, and a bit narrower, as it was meant to be used on EMD switchers. The Details West part might be a bit too big to fit. There also are some brass ones (Overland, I think) that are very nice. I'd still like to figure out how to do the one-piece spark arrestor, as I'm doing an H12-44, plus a few of the H10's carried them. Given the new Walthers H10's coming out, I'm wondering if a communication about this item would be of interest to DA and/or DW. Ken
I cannot seem to find a suitable photo for determining the overall size. It looks sort of like a rectangular box with a curved screen on top. Would it be more complicated than that? If this is correct - one could be made using a piece of base stock with a half round attached to the top, covered with a small piece of nylon leg hose glued on to simulate the wire.
Ken, I think someone can probably fill in the blanks better than I - I recall reading somewhere that these types of spark arrestors were "legislated" in the mid-1960s? I think I may have read this after I realized that my weathering job on my lone F7A make it look like a unit ready to be repainted in O/W!
